2) Writes the results to the output stream stream.3) Writes the results to a character string buffer. The behavior is undefined if the string to be written (plus the terminating null character) exceeds the size of the array pointed to by buffer....
printf_sandfprintf_s behave identically except that printf_s writes output to stdout rather than to a destination of type FILE. For more information, seefprintf_s, _fprintf_s_l, fwprintf_s, _fwprintf_s_l. wprintf_s is a wide-character version of printf_s; format is a wide-c...

wprintf_s is a wide-character version of printf_s; format is a wide-character string. wprintf_s and printf_s behave identically if the stream is opened in ANSI mode. printf_s doesn't currently support output into a UNICODE stream.

using these functions is simplified by template overloads. The overloads can infer buffer length automatically, eliminating the need to specify a size argument. And, they can automatically replace non-secure functions with their secure counterparts. For more information, seeSecure template overloads...

2 sprintf，是把格式字符串输出到指定字符串中，所以参数比printf多一个char*。那就是目标字符串地址。
